ABSTRACT:
A bicolor indicator is provided for a lighting control system which controllably switches one or more lkighting fixtures on or off in accordance with detected motion, ambient light level and a selected time out period. The indicator indicates when the lighting control system is operating in a bypass on or off mode (i.e., overriding controlled switching based on motion detection and ambient light level) or in an automatic time out mode. The indicator also indicates occurrences of motion detection and whether or not the ambient light level is exceeded.
